1. 30S Applied Math Mr. Knight – Killarney School Slide 1 Unit: Systems of Linear Equations Lesson: SLE-L1 Intro to Systems of Linear Equations Find x 3(x - 2) = 2x + 3(x + 5) - 1 Learning Outcome B-1 SLE-L1 Objectives: Review techniques used to solve simple equations

2. 30S Applied Math Mr. Knight – Killarney School Slide 2 Unit: Systems of Linear Equations Lesson: SLE-L1 To solve an equation 2x - 4 = 8 means to find the value for the variable in the equation that will make both sides of the equation equal. In this case, x = 6 would make the left side and the right side of the equation balance, thus creating a true statement. Left SideRight Side 2(6) – 4 =8 12 – 4 =8 8 =8 (True) Theory – Solving an Equation
